FLEXIBLE WRENCH.

. Application filed November 3, 1921. Serial lilo. 512,493.

To all whom 2'25 may concern Be it known that I, HOWARD AUSTIN, a citizen of the United States of America. residing at 1616 Kilbourne Place, Washington, District of Columbia, have invented certain new and useful Improvements in Flexible l/Vrenches, of which the following is a specification.

My invention relates to improvements in flexible wrenches.

Some of the objects of my invention are to construct a wrench which may be manufactured with small expense, which will stand rough usage without injury and which may be readily and easily operated A further object of my invention is the production of a wrench having a joint which will enable the wrench to be operated when the nut-clasping part of the wrench is at an angle to the handle part from zero to approximately ninety degrees.

A still further object of my invention is to provide a wrench which may be used to operate diiierent sized and shaped nuts.

With these and other objects in view, I have shown one embodiment of my invention in the accompanying drawings in which Figure l is a side elevation.

Figure 2 is a section on line 2"2 of Figure 1.

Figure 3 is a section on line 3 -3 of Figure 1.

Figure 4 is a section on line 4"-4 of Figure 1.

Figure 5 is a side elevation of a modified form with a part of the handle broken away.

The wrench comprises a handle part 1 and a nut-clasping part 2. These parts may be made of seamless drawn steel tubing. or other suitable material. The joint between the two parts is made by reducingin size or tapering. as shown. one end of each part by cutting away a portion of the ends and joining by spot welding or in any other suitable manner the resulting tongues 3 and 4, around a ball 5. The openings 6 and 7 beyond the respective tongues 3 and 4, together with the tapered sides of the tongues and the ball enclosed by them enable the part 2 to be placed at an angle to the part 1, this angle extending to approximately ninety degrees. The tapered tongues enable the two shoulders on the respective parts to act together in turning a nut. The turning movement is assist d by the pin 8, which may be inserted snugly in an opening near the end of the handle 2.

The form of wrench shown in Figure 1 is'merely illustrative and can be used only on the style of nut indicated by Figure 1-; but this wrench may. course, be made to be used on any size and shape of nut.

In Figure 5 is shown a modified form of wrench in which the part 2 is made of two members 9 and 10. The outer member 9 or nut-clasping member 9 is screw-threaded as indicated at 11, to the other member 10 of the nut-clasping portion 2. The member 9 may be locked to the member 10 by a set-screw 12. It will be understood that a set of the member 9 adapted to turn nuts of different sizes and shapes may be used with the form of wrench disclosed in Figure 5.

Having described my invention what I claim and desire to protect by Letters Patent is:

1. A flexible wrench comprising two parts. each of said parts having a closed tongue at one end thereof whereby the two parts are joined.

2. A flexible wrench parts, each of said parts tongue at one end thereof parts are joined and being tapered.

3. A flexible wrench comprising two parts, each of said parts having a closed tongue at one end thereof and a ball. said ball being encompassed by each of said tongues.

4. A flexible wrench comprising two parts, each of said parts having a closed tongue at one end thereof. said ton ues beingtapered. and a ball. said ball being encompassed by each of said tongues.

5. A flexible wrench comprising two parts. each of said parts having a tapered tongue on one end thereof. and a ball. said ball being encompassed by each of said tongues, and said tongues being tapered to form shoulders whereby two pairs of shoulders abut when the handle part of said wrench is turned.

. 6. A flexible wrench comprising two parts, said parts consisting of a handle part and a nut-clasping part, each of said parts having a tongue on one end thereof, and a ball, said ball being encompassed comprising two having a closed whereby the two each of said tongues by said tongues, each of said tongues being narrowed outwardly and said parts on the tongue ends thereof being su'fiiciently cut away to form a joint which will enable the parts to be placed at any angle from Zero to approximately ninety degrees.

7. A flexible wrench comprising two parts, each of said parts having a closed tongue at one end thereof, and a member, said member being encompassed by each of said tongues.

S. A flexible wrench comprising two parts, each of said parts having a tongue at one end thereof whereby the two parts are joined, and each of said tongues being free to move with respect to the other of said tongues.

9. A flexible wrench comprising two parts, each or said parts having a tongue at one end thereof, and a member, said member being placed between said tongues and said member being free to move between said tongues.

In testimony whereof I Iny signature.

HOWARD AUSTIN.
